Zusammenfassung:Among the different possible cyclizations leading to nitrogen-containing heterocycles, iminium ion cyclization is a widely used process exemplified by some very famous, and old, reactions. Numerous examples of iminium ion cyclizations can be found in the asymetric total synthesis of complex structures where, very often, they represent the key step.
